True Circuits Attends the TSMC 2017 NA OIP Ecosystem Forum

Showcases State-of-the-art Ultra PLL and Low Power IoT PLL
Brian Gardner presents on Overcoming Timing Closure Issues in Memory Subsystems 

Who

True Circuits, Inc. (TCI), a leading provider of analog and mixed-signal intellectual property (IP) for the semiconductor, systems and electronics industries and member of the TSMC IP Alliance since 2004.

What

True Circuits will showcase its IoT PLLs that are specifically tailored to the stringent power requirements and wide frequency operation range of the rapidly-growing IoT market.  Sipping only 45uW at 30MHz and running from core power, the IoT PLL is designed for very low power.  With multiplication factors up to 8192, the PLL is able to run off of a small and inexpensive 32KHz crystal and still clock a 32-bit CPU at up to 250MHz.  The IoT PLL is ideal for applications like wearables and senor devices, where the power-performance profile must be managed tightly, and possibly over a very wide frequency range.

True Circuits will also showcase its high-performance Ultra PLLs that are well suited for the most demanding chip applications, including high-speed SerDes and ADC input clocks.  The Ultra PLL employs a state-of-the-art architecture and uses high-speed digital and analog circuits to achieve exceptional performance, with many useful features.  It has ultra- low jitter (<500fs) for the most demanding SerDes and ADC input clocks.  It has ultra-wide frequency range with multiplication factors from 3 to over 250,000, supporting reference clocks as low as 32KHz.  It also has precise frequency control with a least 26 fractional bits (at least 10 precise) for extremely high fractional-N resolution.  It can even generate precise and adjustable frequency spreading with programmable rate and depth to meet tight FCC requirements.  The Ultra PLL packs all these features into a compact size that draws low power and, with full pin programmability, one PLL can be used for all applications on a SoC.

True Circuits will also feature its complete line of standardized and silicon-proven general purpose, clock generator, deskew, and spread spectrum PLLs, and multi-slave and multi-phase DLLs that spans nearly all performance points, features and foundry processes typically requested by ASIC, FPGA and SoC designers.  These high quality, low-jitter PLL and DLL hard macros are suited to a wide variety of interface standards and chip applications.  They are pin-programmable, highly process tolerant, reusable and available for delivery in TSMC processes from 180nm to 7nm, including most half nodes.

Brian Gardner, True Circuits' V.P. of Business Development, will make an OIP presentation titled “Overcoming Timing Closure Issues in Wide Interface DDR, HBM and ONFI Subsystems”.  In wide chip interfaces like DDR, HBM and ONFI, it can be challenging to synthesize and connect high-frequency controllers to the PHY hard macros.  Clock trees can be expansive, pushing tools to their limits, and often multiple clock domains are needed.  Jitter can also be an issue on long paths.  Brian will show how True Circuits PLL and DLL IP is being used by multiple customers to build ONFI and HBM subsystems in advanced TSMC process nodes, and discuss the tradeoffs and timing budget concerns among different timing architectures.  In addition, he will explain how source-synchronous signaling is used in our DDR PHY to ease timing closure, and to allow the memory controller to be synthesized for high-frequency operation, which reduces its size and lowers its latency. By using a soft IP "shim" between the memory controller and PHY, the memory controller only needs a single localized clock tree, reducing mismatch and jitter.  The long routes between the soft shim and the PHY hard macros are source-synchronous, so data/strobe groups need only be roughly matched, something easily accomplished by place and route tools.
